FINGER-RING.

SPECIFICATION forming part of Letters Patent No. 783,445, dated February 28, 1905.

Application filed September 24, 1904. Serial No. 225,760.

To all II/71 0717 it may concern.-

Be it known that 1, JOHN A. LIEB, Jr., a citizen of the United States, and a resident of Newark, in the county of. Essex and State of New Jersey, have made and invented certain new and useful Improvements in Finger- Rings, of which the following is a specification.-

My invention relates to an improvement in linger-rings,and more particularly to that kind so constructed that the initial or other ornament may be detached to allow of the substitution of another.

The object of the present invention is to devise an improved fastening means whereby the initial or ornament may be quickly and readily attached and detached from the ring and which fastening means shall be simple in construction, effective in use, and so arranged that the appearance of the ring is in no way marred thereby.

\Vith these and other ends in view the invention consists in certain novel features of construction and combinations of parts, as will be hereinafter fully described, and pointed out in the claims. v

In the accompanying drawings, Figure 1 is a top plan view of a ring, showing the initial secured thereto. Fig. 2 is a similar view showing the initial detached, and Fig. 3 is a plan view of the reverse side of the initial. Fig. t is a sectional view through the ring, showing the attaching-screw. Fig. 5 is a sectional view taken on the line 5 5 of Fig. 1, and Fig. 6 is a sectional view taken on line the 6 6 of Fig. 5. Fig. 7 is a sectional view taken on the line 77 of Fig. 5. Fig. 8 is a detached View of the camscrew. Fig. 9 is a detached view of the capplate.

Referring to the drawings, A represents a ring provided with an enlarged oval-shaped portion B, the latter being hollowed out to form a recess C for containing the fastening means hereinafter referred to, a small opening being formed entirely through the metal for containing the head of the cam-screw D. This cam-screw is constructed with a head a, provided with the slot 5 for the reception of the end of the screw-driver or other instrument to turn the same, and with the wings 0 (Z.

The outer extreme edges of these wings or sides form eccentrics, the upper surfaces of which are beveled and are cam-shaped, whereby when the screw is turned the outer eccentric edges will bind against the sides of the lugs on the initial, as hereinafter explained, and the beveled cam edges at the same time pull or force downwardly these lugs, resulting in securely holding the initial in place.

E represents the cap-plate fitting over the opening or recess Gin the ring-head and over the cam-screw, as illustrated in Figs. 2 and 6, said plate being provided with the notches or recesses 6, through which the lugs on the initial pass when the parts are properly assembled.

F represents an initial or ornament provided with the lugs f, the lower extreme ends of which are bent inwardly and beveled, as illustrated in Fig. 5, said lugs extending through the recesses e in the cap-plate and down into the recess C,'the under flat side of said initial or ornament resting upon the capplate E.

As illustrated in the several figures of the drawings, the surface of the head of the camscrew D lies flush with the under surface of the ring-head and is the only part visible of the fastening means after the several parts have been properly assembled. \Vhen this cam-screw is turned by means of a proper tool, the eccentric edges of the sides or wings 0 (Z bind against the inner sides or surfaces of the luE fOD the initial F, the beveled camsurfaces of the wings at the same time bearing against the inwardly-turned beveled ends of said lugs, thereby forcing dmvnwardly or inwardly these lugs and the attached initial or ornament, the latter being thereby forced tightly against the ring-head and cap-plate E. By turning backwardly said cam-screw it is brought into a position whereby the lugs on the initial are released, thereby allowing said initial to be withdrawn or detached and another substituted. It will thus be seen that the cam-screw by reason of its peculiar formation operates to bind or hold the lugs of the initial in two different directionsthat-is, the eccentric edges of the wings 0 d bind the lugs in a lateral direction, while the beveled cam edges or surfaces bind the extreme ends of the lugs in a vertical direction.

Having fully described my invention. what I claim as new, and desire to secure by Letters Patent, is

1. A ring provided with a head formed with a recess and an opening extending from said recess entirely through the head, in combination with a cam-screw the end of which extends through said opening in the ring-head and formed with wings having eccentric edges and lower beveled cam-surfaces, a cap-plate fitting over said recess and initial or ornament provided with lugs extending through said cap-plate and into said recess and engaging with said cam-screw, substantially as described.

2. The combination with a ring formed with a head in which is provided a recess and an opening extending through said head, of a cam-screw contained within said recess and formed with an end extending through said opening in said ring-head, said cam-screw be ing provided with wings having outer eccentric edges and lower beveled cam-surfaces, a cap-plate fitting over said recess in said ringhead and an initial or ornament provided with lugs, the lower extreme ends of which are turned inwardly and beveled, whereby when said cam-screw is turned, the outer eccentric edges thereof bind against said lugs and the cam-surfaces against the beveled ends of said lugs, substantially as described.

Signed at New York, borough of Manhattan, in the county of New York and State of New York, this 21st day of September, A. D. 1904.
